SHAFT-COUPLING.

Specification of Letters Patent.

Application filed July 24, 1916. i Serial N o. 111,053.

To all whom t may concern.'

Be it known that I, BENJAMIN F. AUGUS- I TINE, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Shaft-Couplings, of

which the following is a specification.

This invention relates to shaft couplings.

One object is to provide a shaft coupling wherein, one coupling member is pulled by the other and wherein the pulling connections between the coupling-members have universal joint connections with the members and are housed within the latter.

Another object resides in the provision of a shaft coupling, embodying among other characteristics, coupling members constructed so that they may be reversed and either Serve as the driving or driven member and wherein the driven member is pulled by the driving member through the instrumentality of suitable positive connectionsbetween the members and whose connections with the members are such as to provide for a safety.

liexible connection that will permit of thc coupling shafts running in or slightly out ot alinement.

lVithlthe above and other objects in view, the present invention consistsV in thed combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being 'understood that changes may be made in the form, size, proportion and minor details without departing from the spirit or sacricing any of the advantages of the invention. Y

In the drawings- Figure 1 is a view of the outer face of one of the coupling members.

Fig. 2 is-a sectional view illustrating the shafts slightly out of alinement.

Fig.l 3 is a transverse sectional View. A Fig. t is a sectional view on the line 1 4 of Fig. 3.

Referringl now more particularly to the accompanylng drawings, 10 and 11 indicate coupllng members,leach formed alike, forv reversing purposes. Each member includes a body portion 9, outwardlyl directed hubs 12 and 13, respectively, and inwardly directed marginal annular flanges 14 and 15, respectively, whereby each coupling member is of cup-formation, designed to'have such cooperative relation when theA coupling is as-` the latter.

The coupling members 10-and 11 are fixedly secured to the driving and driven shafts 21 and 22, respectively, by means of suitable keys 23 and 24, respectively. v-

Pulling li ks 25, 26 and 27 are connected to the coupling members so that the coupling member 11 may be pulled by the coupling member 10 upon operation of the driving shaft 21. `These pulling linksare of peculiar formation.` As shown, each link is provided with heads 28 and 29 located at the ends of each link. Each head is provided with an aperture 30 in which is tted a sectional brass or other wear ring 31 provided with an annular internal groove 32 forming a bearing. A ball 33 is movably. mountedin the wear ring 31 and is provided with a smooth central bore 311. The wear ring sections are held in place by upsetting the heads 28 and 29 adjacent the apertures 30,`as indicated at 30.

Bolts A pass through the bores 34 of the balls to connect the links to the Yrespective coupling members.V Each bolt A has a conical head 35 provided with a recess 36 to take a screw driver. Each b olt is smooth'adjacent the conical head 35, as at a, and it is this smooth portion ofeachbolt which takes the bore 34 of therespective ball 33. Each bolt has a cone bearing mounted thereon as shown atV 37, adjacent the outer end of the smooth portion a and from the cone bearing each bolt is screw-threaded, as shown at 38.

The bolts A are passed 'through the balls 33 in the heads of each link in opposite directions, that is tosay, a. bolt A is passed through the ball 33 inthe head 28 of the link 25 with its screw-threaded end screwed Patented` Get. 16,1917.,4`

member 10. A jamnut 39 is then screwed onto the screw-threaded end of such bolt and located in the recess 16 of the coupling mem-' 4o of'breakage ofithe pulling connections. It

`ber A rheball is journaled on` the smooth portion.. a ofthe bolt. A cone bearing 37 .coop rates with the cone-shaped head 35 of the -b t A to provide bearings for fthe side sur- .faces of -the .balls r A bolt A is then passed through the ball 33 in the head 29 at the opposite ,end ofthe -link25 in a direction opposite-to the direction of passage of the'bolt previously passed through the ballv in the head 28 and having `its screw-threaded end screwed into and through thecorresponding aperture 19 and into-the respective recess 17' of the coupling 'member 11 and a jam nut applied to the bolt vand located in said respective recess, whereby, each link is connected at-one end to one coupling member and at its opposite endto thecompanion coupling member so that ro- .tation of the driving coupling member will.

produce a pulling action on the driven coulpling ymember.

Todisassemble the partsof the coupling or. to adjustthe bolts with relation to the 7 universalconnection, a screw. driver or other 25.

l serted through the openings 20 to engage in suitable element (not shown) maybe inthe recesses 36 of the respective bolts to turn the" bolt and disconnect it from the respective nut 39, or for adjustment purposes, said.

nuts 39 being held against vr tation in any 'suitable' manner during adjustment of the. bolts or during disconnection of the bolts from the nuts.

` cou/plingin that the. driving vconnections be#4 tween the couplingv members are housed within the coupling members obviating pos- The construction illustrated and described, provides for *an eiicient liexible coupling andone which may be regarded as a safety sibilty of danger to bystanders in the event .l s will also be apparent lthat-by virtueI of the universal joint connections between the pulling links and the coupling members that the coupling membersmay readily tilt, relative to' each other and provide` for an effective 4connection between the driving and driven shafts inthe event that they should .assume positions slightly out of-alinement" What I claim isr'- 1. A shaft coupling comprisingcoupling members, each cup-shaped in form and each fprovlided with equiv-distant recesses in its outer face with screw-threaded apertures leading inwardly from the recesses and each also having'ape'rtures arranged between the aforesaid recesses, links disposed between the coupling members, each having a perforated head, a ybored ball rotatably mounted in each head of `each link, and bolts. passed through' thebores of the balls and connecting the ends vof each link'lto opposite cou pling members. Y

2. A shaft coupling comprising cup shaped coupling members, links -arranged between said couplingmembers, a ball rotatably mounted in each end of each link, and.

adjustable bolts mounted in each coupling member and extending therethrough on which the rotatably mounted balls are journaled, said coupling members having a plu 'rality of apertures through which said bolts bers onwhicli saidrotatably mounted balls are journaled.

shaft coupling comprising cupshaped couplingfniem'bers, links arranged y i between said members, a ball rotatably mounted in each end of each link, bolts mounted in each coupling member and extending therethrough and each' havinga conical head on its 'inner end, and a cone bearing mounted on each bolt, said rotatably mounted balls being j ournaled on the Iinner ends of said bolts, said conical head and vcone bearing forming bearings for said balls. A

5. A shaft coupling comprising coupling members, links arranged vbetween said members, adjustable bolts mounted in said coupling members, a universal connection between said boltsand each end of each link,

and a jam nut mounted on one end of each bolt, each bolt having a conical head provided with a notch therein, said coupling l members having apertures extending therethrough in alinement with said bolts, whereby said bolts may be. adjusted with reference to the vuniversal connection by means of tools inserted through said apertures.

6. .A shaft coupling comprising coupling fmembers, 'relatively' short links arranged bey tween saidcoupling members, all of the linksbeing formed alike, a ball rotatably mounted in each end ofl each link, and bolts extending through each coupling member, alternate bolts extending through the coupling members and connecting with one of the balls of each link, veach coupling member having apertures extending therethrough inl alinement with said bolts, whereby the bolts may be adjusted orv disconnected from the respecf tive coupling members.' y
